Joseph Caspar (born 1799 in Rorschach, Switzerland; died 1880) was a Swiss painter and engraver.
When Caspar was 16 he went to Rome and studied there by copying the works of Old Masters.
Following Wilhelm von Schadow's advice, Caspar went to Berlin in 1820.
The privy council of Beuth (German: Geheimrat von Beuth) advised him to specialize in copper engraving and supported him financially.
He later became Giuseppe Longhi’s and Pietro Anderloni’s student for about four years in Milan.
